CROSS REFERENCE TO RELATED APPLICATION

This application claims the benefit of U.S. Provisional Application No. 61/655,417, filed on Jun. 4, 2012, which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

This disclosure features combinations that include a paraffinic oil and one or more anti-settling agents, which are useful, e.g., for promoting the health of a plant (e.g., turf grass), e.g., controlling a disease, condition, or injury caused by a pest of a plant.

BACKGROUND

Grasses are often planted and maintained to provide aesthetically pleasing or recreationally useful groundcover for an area of land, which may be called a lawn, turf, pitch, field or green depending on the context. Species of grasses that are maintained in this way are sometimes referred to as turf grasses. Turf grass care and maintenance has a rich horticultural tradition, reflecting in part the numerous economic and environmental benefits provided by turf grasses (see, for example, Walsh, B. et al., HortScience, 34, 1999, 13-21).

A number of different management practices for controlling a variety of turfgrass pests are known. For example, cultural practices for maintaining turfgrass health may include the selection or substitution of turfgrass species or cultivars that are not susceptible to certain pests. Implementing a fertility program that promotes turfgrass vigor may also decrease the turfgrass' susceptibility to certain pests. Adjustment of mowing practices, for example, cut height and frequency, may also be included in a management program. Extended periods of leaf wetness may also render turfgrass more susceptible to disease. Accordingly, moisture management practices, including proper irrigation, drainage and dew removal may improve turfgrass health. Cultural practices for controlling turfgrass pests may also include proper thatch control and aerification.

In addition to cultural management practices, chemical pesticides have been developed and used to control plant pests. For example, a number of chemical fungicides based on similar or different modes of action are known. The use of conventional fungicides, however, has several disadvantages. For example, a number of conventional chemical fungicides are site specific in that they disrupt single metabolic processes or structure sites of the target fungus. Accordingly, strains may develop resistance to the fungicide after repeat applications. Conventional fungicides generally have a poor environmental profile and their use can be expensive. Thus, it is desirable to limit the amount of fungicide used. Furthermore, conventional fungicides are generally not acceptable for use in organic farming.

In an alternative approach to conventional chemical fungicides, oil-in-water emulsions comprising paraffinic oils and paraffinic spray oils have been used for controlling turfgrass pests (see, for example, Canadian Patent Application 2,472,806 and Canadian Patent Application 2,507,482). For example, Petro-Canada produces CIVITAS™, a broad spectrum fungicide and insecticide for use on golf course turf and landscape ornamentals, used for example to control powdery mildew, adelgids and webworms on landscape ornamentals (US EPA REG. NO. 69526-13). Product labeling indicates that CIVITAS™ may be applied as part of an alternating spray program or in tank mixes with other turf and ornamental protection products; and that CIVITAS™ may be used as a preventative treatment with curative properties for the control of many important diseases on turf, including fairways and roughs. In addition, oil-in-water formulations comprising paraffinic oils and a pigment for controlling turfgrass pests have been reported as well as stable composition concentrates including both the paraffinic oil and pigment in a single concentrate have been reported (see, for example, WO 2009/155693). For example, in addition to CIVITAS™, Petro-Canada produces a separate product, CIVITAS™ HARMONIZER, a pigment dispersion. Product labeling indicates that CIVITAS™ HARMONIZER is for use with CIVITAS™ for golf course applications.

SUMMARY

[1] This disclosure features combinations that include one or more paraffinic oils and one or more anti-settling agents.

[2]

It has been observed previously that compositions having a paraffinic oil, an oil-dispersible pigment, a surfactant and a polyethylene glycol (“PEG”) can be stored prior to application to a plant (e.g., a turf grass). These compositions are sometimes referred to as “one-pack formulations” and offer the safety and convenience of having all active components pre-mixed by a manufacturer instead of by the end user. However, while convenient, such compositions can sometimes produce an unacceptable color in the grass and/or cause phytotoxicity to the plant. The compositions may also form hard settling during storage. While not wishing to be bound by theory, it is believed that the foregoing could be caused, in part, by the presence of the polymer components used in the oil-dispersible pigment to facilitate the incorporation of the pigment into the composition.

It has also been observed previously that separately packaged and storable water-dispersible pigments can be combined with a paraffinic oil to form a mixture that is emulsified prior to application to a plant (e.g., a turf grass). The separately packaged water-dispersible pigment/separately packaged paraffinic oil combinations are sometimes referred to as “two-pack formulations” (e.g., CIVITAS™ 2-pack) and have been found to be generally effective for, e.g., promoting the health of a plant.

Attempts to combine the safety and convenience aspects of the one pack formulations with the performance aspects of the two-pack formulations (e.g., combining and emulsifying a water-dispersible pigment and a paraffinic oil for purposes of providing a storable emulsion) have resulted in products that tend to have commercially undesirable stability, shelf life, and/or performance. This is believed to be due primarily to the occurrence of irreversible coalescence and/or settling out of the pigment.

[3]

It has been surprisingly found that product stability, shelf life, and performance can be significantly enhanced by the inclusion of one or more anti-settling agents in combinations that include one or more pigments (e.g., in the form of water-based pigment dispersions) and one or more paraffinic oils.

As used herein, the term “anti-settling agent” refers to a dispersible substance, which when introduced into a solid (dispersed phase)-liquid (continuous phase) dispersion or suspension, substantially prevents the solid portion of said dispersion or suspension from undergoing coalescence, settling (e.g., due to gravity), and/or any other process(es) that cause(s) the solid portion to become a solid mass (e.g., a solid mass that is hard and/or compacted) that cannot be re-dispersed or re-suspended.

As used herein, the term “substantially prevents” means that the anti-settling agent prevents at least 50% (e.g., at least 60%, at least 70%, at least 80%, at least 90%, at least 95%, at least 99%) of the solid portion to become a solid mass (e.g., a hard and/or compact solid mass) that cannot be substantially re-dispersed or re-suspended (e.g., as determined by measuring the height of the solid settling in a clear bottle during storage test).

[4]

The pigments themselves tends to be generally heavy (e.g., has a higher density and/or specific gravity than the oil and water) and tend to settle to the bottom of the liquid medium when stored for extended periods in the absence of an anti-settling agent. It is believed that the anti-settling agents prevent these pigments from forming, e.g., a coalesced solid mass (e.g., a solid mass that is hard and/or compacted and cannot be re-dispersed or re-suspended). While not wishing to be bound by theory, it is believed that the presence of one or more anti-settling agents imparts rheological changes to the paraffinic oil-based combinations by forming a 3-dimensional structure in the oil, which reduces or slows down the settling of solids (e.g., pigments) in the combinations described herein (e.g., settling of one or more pigments, e.g., one or more pigments in the form of a water-based pigment dispersion). In some instances, it is believed that the anti-settling agents can impart such changes by binding to the pigment. In addition, even though some aggregation and dropout of solids (e.g., pigments) may occur, the presence of the anti-settling agent allows any aggregated solid to be re-dispersed through simple agitation. Solid (e.g., pigment) re-dispersion generally does not occur in the absence of the anti-settling agent.

It is also believed that subjecting the combinations to a high-shear processing step (e.g., using high speed mixers such as a dissolver, rotor-stator mixer, bead mill or homogenizer) can more efficiently disperse the anti-settling agent in the oil, and in some instances, reduce the particle size of solids in the combinations that tend to settle (e.g., reduce the particle size of the one or more pigments, e.g., reduce the particle size of the one or more pigments in the form of a water-based pigment dispersion).

Advantageously, the irreversible drop-out of solid aggregates is reduced or slowed in the combinations described herein, which enhances the stability of the combinations and can further extend their useful shelf life.

[4]

The combinations typically further include (but are not limited to) one or more of the following: one or more emulsifiers, one or more pigments (e.g., a water-based pigment dispersion), one or more silicone surfactants, one or more other chemical fungicides, and water.

This disclosure features stable and storable combinations that include one or more water-based pigment dispersions. Typically, such combinations are prepared by processes that include emulsification of the combinations followed by mechanical dispersion of the resultant emulsions.

Methods of formulating combinations that include both oil and water as oil-in-water (O/W) emulsions are also featured.

In some implementations, the combinations can be in the form of a single composition (e.g., a concentrate, e.g., which is contained within a storage pack or a vessel (e.g., a tank) suitable for applying the composition to a plant, e.g., turf grass). The components that form part of said single composition can affect, e.g., controlling a disease, condition, or injury caused by a pest of a plant. The combinations described herein therefore provide ease-of-use since the components, which achieve, e.g., the controlling a disease, condition, or injury caused by a pest of a plant, are present in a single composition and need not be combined by the end-user.

In some implementations, the composition is a concentrate. As used herein, the term “concentrate” refers to a combination (e.g., a single composition) that is free of water or includes small amounts of water (e.g., 3 parts per weight) due primarily to the inclusion of water from a water-based pigment dispersion. Typically, such compositions are applied to a plant (e.g., turf grass) after dilution with water.

In some implementations, the combinations described herein can be prepared, stored, and transported in concentrated (e.g., undiluted) form (and still, e.g., exhibit one or more of the advantages described above), which conveniently reduces the volume of product sold to, and manipulated by, the end-user.

This disclosure also features methods of using the combinations for promoting health of a plant (e.g., turf grass), including but not limited to controlling a disease, condition, or injury caused by a pest of a plant. Also featured are uses of the combinations for promoting health of a plant (e.g., turf grass), including but not limited to controlling a disease, condition, or injury caused by a pest of a plant (as well as uses in the manufacture of a composition for such purposes). In some implementations, other conventional agent(s) can be included for such a purpose.

[7] DEFINITIONS

As used herein, the term “oil-in-water emulsion” refers to a mixture in which one of the paraffinic oil and water (e.g., the paraffinic oil) is dispersed as droplets in the other (e.g., the water). In some implementations, an oil-in-water emulsion is prepared by a process that includes combining the paraffinic oil, water, and any other components and the paraffinic oil and applying shear until the emulsion is obtained. Typically a white milky color is indicative of the formation of an emulsion in the absence of any pigment; and a green color is observed in the presence of a pigment. In other implementations, an oil-in-water emulsion is prepared by a process that includes combining the paraffinic oil, water, and any other components in the mixing tank and sprayed through the nozzle of a spray gun.

As used herein, the term “controlling infection of a plant by a biotic agent” (and the like) means to diminish, ameliorate, or stabilize the infection and/or any other existing unwanted condition or side effect that is caused by the association of a pest organism with the plant include fungi, oomycetes, bacteria, viruses, viroids, virus-like organisms, phytoplasmas, protozoa, nematodes, parasitic plants and insects.

As used herein, the term “control a fungal pathogen of a plant” or “control a disease caused by a fungal pathogen” (and the like) means to diminish, ameliorate, or stabilize the disease and/or any other existing unwanted condition or side effect that is caused by the association of a fungal pathogen with the plant.

As used herein, the term “controlling infection of a plant by a fungal pathogen” (and the like) means to diminish, ameliorate, or stabilize the infection and/or any other existing unwanted condition or side effect that is caused by the association of a fungal pathogen with the plant.

As used herein, the term “controlling a disease, condition, or injury caused by a pest of a plant” (and the like) means to diminish, ameliorate, or stabilize the disease, condition, or injury and/or any other existing, unwanted condition(s) or side effect(s) that caused by the association of a pest of a plant with the plant.

As used herein, the term “pest of a plant” (and the like) is used to refer to living organisms occurring on plants that are not desired to occur on plants or that cause injury or disease to plants. Examples include fungi, bacteria, viruses, spiders, ticks, mites, nematodes, gastropods and insects.

As used herein, the term “turf grass” refers to a cultivated grass that provides groundcover, for example a turf or lawn that is periodically cut or mowed to maintain a consistent height. Grasses belong to the Poaceae family, which is subdivided into six subfamilies, three of which include common turf grasses: the Festucoideae subfamily of cool-season turf grasses; and the Panicoideae and Eragrostoideae subfamiles of warm-season turf grasses. A limited number of species are in widespread use as turf grasses, generally meeting the criteria of forming uniform soil coverage and tolerating mowing and traffic. In general, turf grasses have a compressed crown that facilitates mowing without cutting off the growing point. In the present context, the term “turf grass” includes areas in which one or more grass species are cultivated to form relatively uniform soil coverage, including blends that are a combination of differing cultivars of the same species, or mixtures that are a combination of differing species and/or cultivars.

Examples of turf grasses include, without limitation:

DETAILED DESCRIPTION

This disclosure features combinations that include one or more paraffinic oils and one or more anti-settling agents. The combinations typically further include (but are not limited to) one or more of the following: one or more emulsifiers, one or more pigments, one or more silicone surfactants, one or more other chemical fungicides, and water. In some implementations, the combinations can be in the form of a single composition (e.g., a concentrate, e.g., which is contained within a storage pack or a vessel (e.g., a tank) suitable for applying the composition to a plant, e.g., turf grass). Typically, such compositions are applied to a plant (e.g., turf grass) after dilution with water. This disclosure also features methods of using the combinations for promoting health of a plant (e.g., turf grass), such as controlling a disease, condition, or injury caused by a pest of a plant. In some implementations, other conventional agents can be included for such a purpose. Methods of formulating combinations that include both oil and water as oil-in-water (O/W) emulsions are also featured.

I. Components

[A] Paraffinic Oil

The paraffinic oil confers properties (e.g., fungicidal properties) that are useful for promoting the health of a plant (e.g., turf grass). While not wishing to be bound by theory, it is believed that the paraffinic oil is able to provoke an induced systemic resistance (ISR) response, a systemic acquired resistance (SAR), or other defense response in a plant.

[1]

In some implementations, the paraffinic oil includes an oil enriched in paraffin.

In certain implementations, the paraffinic oil includes a paraffin having from 12 carbon atoms to 50 carbon atoms (e.g., 12 carbon atoms to 40 carbon atoms, 16 carbon atoms to 35 carbon atoms, 12 carbon atoms to 21 carbon atoms; e.g., 16 carbon atoms to 35 carbon atoms).

In certain implementations, the paraffinic oil includes a paraffin having an average number of carbon atoms that is less than or equal to about 20 (e.g., 16).

In certain implementations, the paraffinic oil includes a paraffin having an average number of carbon atoms of from 16 to 30 e.g., 23 or 27).

In certain implementations, the paraffinic oil includes a paraffin having from 16 carbon atoms to 35 carbon atoms and an average number of carbon atoms of 23.

In certain implementations, the paraffin is an isoparaffin (e.g., a synthetic isoparaffin manufactured from two-stage Severe Hydrocracking/Hydroisomerization process).

In some implementations, a paraffin is present in the paraffinic oil in an amount, that is at least 80% (e.g., at least 90%, at least 99%).

[2]

In some implementations, the paraffinic oil has been refined to remove compounds that are associated with plant injury, for example, aromatic compounds or compounds containing sulfur, nitrogen, or oxygen. In certain implementations, the paraffinic oil includes relatively low levels of aromatic compounds and/or compounds containing sulfur, nitrogen, or oxygen, e.g., less than 10 weight percent (less than 5 weight percent, less than 2 weight percent, less than 0.5 weight percent) of aromatic compounds and/or compounds containing sulfur, nitrogen, or oxygen.

[3]

Non-limiting examples of suitable paraffinic oils include, HT60, HT100, High Flash Jet, LSRD, and N65DW (available from Petro-Canada, Calgary, AB, Canada). In certain implementations, the paraffinic oil is N65DW.

[B] Emulsifier

In some implementations, the combinations include paraffinic oil, emulsifier, and water. It can be advantageous to store and/or apply such combinations as oil-in-water (O/W) emulsions.

Emulsions tend to be thermodynamically unstable due to excess free energy associated with the surface of the dispersed droplets such that the particles tend to flocculate (clumping together of dispersed droplets or particles) and subsequently coalesce (fusing together of agglomerates into a larger drop or droplets) to decrease the surface energy. If these droplets fuse, the emulsion will “break” (i.e., the phases will separate) destroying the emulsion, which in some cases can be detrimental to the storage shelf-life of the combinations. While not wishing to be bound by theory, it is believed that the addition of one (or more) emulsifying agents or emulsifiers can prevent or slow the “breaking” of an emulsion. As the skilled artisan will appreciate, the type and concentration of a particular emulsifying agent will depend, inter alia, on the emulsion phase components and the desired result.

[1]

In some implementations, the emulsifier is a “fast break” or “quick break” emulsifier. While not wishing to be bound by theory, it is believed that a “fast break” or “quick break” emulsifier allows the paraffinic oil to be quickly released from the O/W emulsion upon application to the plant for contact, e.g., with a plant pest. When a “fast break” or “quick break” emulsifier is present in a suitable amount (for example a selected proportion or ratio with respect to the paraffinic oil), the resulting “fast break” or “quick break” O/W emulsion quickly releases the oil phase upon application to the turfgrass. As such, there is less runoff of the O/W emulsion from, e.g., the grass blades (as compared to more stable O/W emulsions) resulting in more oil adhering to the plant, e.g., turfgrass for a longer period of time to more effectively contact and control, e.g., associated fungal pathogen. In certain implementations, the oil phase resides on the plant, e.g., turfgrass for a period of not less than one hour. In certain implementations, the oil phase resides on the plant, e.g., turfgrass for a period of from not less than 1 hour but not more than 30 days. In certain implementations, the “fast break” or “quick break” emulsion may be, for example, an emulsion having an oil phase that, after mixing with water, is reconstituted in 0.5 to 15 minutes according to the following test:

-   -   1. Fill 100 mL graduated cylinder with tap water.     -   2. Add 1 mL of emulsified oil.     -   3. Invert graduated cylinder 5 times.     -   4. Using a stop watch and human observation, measure how long it         takes for the oil phase to reconstitute after inversion (step         3).

In some implementations, the oil phase is reconstituted in from 2 minutes to 5 minutes according to the test described above. In some instances, the “fast break” or “quick break” property of the O/W emulsion is balanced with the need to provide an O/W emulsion with a suitable shelf life under suitable storing conditions, and for a suitable timeframe.

[3]

In some of the implementations described in sections [II][A][1] and [II] [A][2], the compositions and concentrates further include water, and are in diluted form. As used herein, the expression “in diluted form” means that the amount of water present is greater than the amount of water that would be present due to the inclusion of a water-based pigment dispersion. In certain implementations, the amount of water present is sufficient to form an oil-in water emulsion as described anywhere herein.

In certain implementations, weight percent ratio of the undiluted composition to water is from 1:1 to 1:100 (e.g., from 1:50, 1:30, 1:20, 1:15, 1:10).

III. Application of Combinations

[A] In general, the combinations can be applied to the plant by conventional methods known in the art, e.g., spraying, misting, sprinkling, pouring, or any other suitable method.

In some implementations, the combinations include both paraffinic oil and water. It is advantageous to apply such combinations as oil-in-water (O/W) emulsions. In some implementations, an oil-in-water emulsion is prepared by a process that includes combining the paraffinic oil, water, and any other components and the paraffinic oil and applying shear or shaking vigorously (e.g., for 30 seconds) until the emulsion is obtained. In other implementations, an oil-in-water emulsion is prepared by a process that includes combining the paraffinic oil, water, and any other components at the nozzle of a spray gun. In certain implementations, agitation is maintained throughout mixing and/or application of the combinations.

Foliar Applications

In some implementations, the combinations are applied by foliar application (e.g., by applying to the aerial exterior portion of the plant, e.g., to the leaves of the plant, e.g., by spraying the plant.

In some implementations, the combination is applied to a plant (e.g., turf grass) at a rate from 1.0 oz/1000 square ft to 50 oz/1000 square ft (e.g., from 1.0 oz/1000 square ft to 40 oz/1000 square ft; from 1.0 oz/1000 square ft to 35 oz/1000 square ft; from 5.0 oz/1000 square ft to 35 oz/1000 square ft; from 5.0 oz/1000 square ft to 15 oz/1000 square ft; from 16.0 oz/1000 square ft to 35 oz/1000 square ft; from 8.5 oz/1000 square ft to 17 oz/1000 square ft; from 17.0 oz/1000 square ft to 34 oz/1000 square ft; 17.0 oz/1000 square ft).

In some implementations, the paraffinic oil is applied to a plant (e.g., turf grass) at a rate from 1.0 oz/1000 square ft to 32 oz/1000 square ft (e.g., from 4.0 oz/1000 square ft to 16 oz/1000 square ft).

In some implementations, the pigment is applied to a plant (e.g., turf grass) at a rate from 0.001 lb/1000 ft² to 0.5 lb/1000 ft².

In some implementations, the combinations are applied by spraying (e.g., using a medium or coarse spray (ASABE standard 572) and the minimum volume mean diameter for spinning atomizer nozzles). In certain implementations, the nozzle height is at most about four feet above ground level.

In certain implementations, the combinations are applied by spraying when the wind speed is equal to or less than 15 mph.

Non-Foliar Applications

In some implementations, the combinations (e.g., compositions, e.g., fungicidal compositions) can be applied to a growing medium (e.g., soil) that is in proximity to a base and root system of the plant, in which the amount of the composition that is applied to the growing medium is sufficient to penetrate the growing medium and contact the root tissue for uptake by the plant.

As used herein, the term “growing medium” refers to any soil (of any composition) or soil-free (e.g. hydroponic) medium that is suitable for growing and cultivating a plant. The growing medium can further include any naturally occurring and/or synthetic substance(s) that are suitable for growing and cultivating a plant.

In certain implementations, the growing medium (e.g., soil) can include any surface of the growing medium that is from 0 inches to six feet (e.g., 0 inches to five feet, 0 inches to four feet, 0 inches to three feet, 0 inches to two feet, 0 inches to 12 inches, 0 inches to six inches, 0 inches to one inch, 0 inches to 0.5 inch) from the base of the plant and any growing medium that is from 0 inches to 24 inches beneath said surface of the growing medium. In other implementations, the length of the surface of the growing medium can be determined on the basis of the height of the plant, e.g., can correspond to the shade radius of the plant (i.e., the distance around the plant that is shaded during daylight hours due to the height of the plant).

In some implementations, applying is carried out by soil drenching (e.g., by pouring the combinations described herein as a bolus on the surface of the growing medium or soaking a plant tray in the combinations described herein, e.g., root bathing).

In some implementations, applying is carried out by drip irrigation.

In some implementations, applying is carried out by soil injection.

In some implementations (e.g., when the plant is a crop plant, e.g., wheat, barley, soybean, tomatoes, potatoes, or corn, or any combination thereof; e.g., wheat or tomatoes), the combinations (e.g., compositions, e.g., fungicidal compositions) further include from 50 to 99 parts per weight of water (e.g., the composition can be an oil-in-water emulsion). In certain implementations, the combinations (e.g., compositions, e.g., fungicidal compositions) can be applied at a rate of from 100 gal/acre to 800 gal/acre (e.g., 200 gal/acre to 400 gal/acre). In certain implementations, the combinations (e.g., compositions, e.g., fungicidal compositions) further includes from 50 to 99 parts per weight of water (e.g., the composition can be an oil-in-water emulsion), and the combinations (e.g., compositions, e.g., fungicidal compositions) can be applied at a rate of from 100 gal/acre to 800 gal/acre (e.g., 200 gal/acre to 400 gal/acre). In certain implementations, the oil can be applied at a rate of from 1 gal/acre to 20 gal/acre.

In some implementations (e.g., when the plant is a tree (e.g., a maple tree, a citrus tree, an apple tree, a pear tree, an oak tree, an ash tree, a pine tree, or a spruce tree, or any combination thereof; e.g., a maple tree), the combinations (e.g., compositions, e.g., fungicidal compositions) further includes from 5 to 99 parts per weight of water (e.g., the composition can be an oil-in-water emulsion). In certain implementations, the oil can be added at a rate of from 1 oz to 2 gallons of the combinations (e.g., compositions, e.g., fungicidal compositions) per inch of tree diameter. In certain implementations, the composition further includes from 5 to 99 parts per weight of water (e.g., the composition can be an oil-in-water emulsion), and the oil can be added at a rate of from 1 oz to 2 gallons of the combinations (e.g., compositions, e.g., fungicidal compositions) per inch of tree diameter.

In some implementations, the combinations (e.g., compositions, e.g., fungicidal compositions) can be applied over a time period of at least ten seconds (e.g., at least five seconds, at least two seconds).

Additional Features(s) to Supplemental Foliar or Non-Foliar Applications

In the above-described implementations, application of any one (or more) combinations can be repeated one or more times.

In some implementations, the application methods described above can further include applying one or more conventional chemical fungicides to the plant (e.g., the one or more conventional chemical fungicides can be applied to an aerial portion of the plant), e.g., when disease pressure is high, e.g., when disease pressure is high and/or when the target disease is one or more of fusarium patch, grey leaf spot, large patch of Zoysia, snow mold (grey or pink), spring dead spot, summer patch, brown patch, crown rust, or dollar spot.

In some implementations, the application methods described above can further include adding water (e.g., to the growing medium) after the composition has been applied. In certain implementations, the methods can further include “watering in” the combinations (e.g., compositions, e.g., fungicidal compositions). For example, the combinations (e.g., compositions, e.g., fungicidal compositions) can be applied first to a growing medium (e.g., soil) and then watered in with, e.g., 0.5 to 2 inches of water.

In some implementations, the combinations are applied to golf courses (e.g., golf course fairways, tee boxes, and/or putting greens).

EXAMPLES Example 1 Effect of Anti-Settling Agent

Referring to FIG. 1, the image on the top (a) shows a mixture of the pigment mixed into the oil. There is immediate aggregation and dropout of solid material. It was not possible to re-disperse the material through agitation, and there was also no benefit to homogenization.

Referring to FIG. 1, the image on the middle (b) shows the effect of the addition of the anti-settling agent in 1-Pack, which was found to reduce the aggregation and dropout of pigment when added to the oil. Over time (weeks, months) some phase separation that occurs; however, this can be reversed through agitation.

Referring to FIG. 1, the image on the bottom (c) shows the effect of the addition of a high shear processing step to disperse the anti-settling agent into the oil. A high shear processing step (using dual-feed operation of Sonolator, Sonic Corp.) further reduces particle size of the pigment and improves the stability.

Example 2

The study below shows dollar spot & brown patch control when treated with Civitas 1-Pack (or Civitas ONE), Civitas+propiconazole 1 pack and compared to Civitas (2-Pack) standard and in combination with chemical fungicides.

The trial was conducted on the ‘research tee’. Treatments were applied using 8004 calibrated to deliver 88 gallons per acre. All application days where rain-free and all treatments were applied to a dry canopy generally mid-morning.

The study was maintained as a typical golf course tee. The site has a history of severe brown patch (Rhizoctonia solani) and dollar spot activity. The turf consisted of ‘Princeville’ creeping bentgrass that was mowed at the height of 0.450 and three times per week. The study area received 1.5 lb N per 1000 ft² from 31-0-0 (IBDU) in winter before the trial.

Dollar spot (Sclerotinia homoeocarpa) was rated on a percent (%) blighted scale from 0 to 100 where 100=total plot area blighted. Percent plot area blighted by brown patch (Rhizoctonia solani) was rated on a percent (%) blighted scale from 0 to 100 where 100=total plot area blighted. Phytotoxicity was rated on a 0 to 5 scale where 2=maximum acceptable from a fungicide application and 5=brown turf. Turfgrass quality was rated on a 0 to 10 scale where 10=optimal turfgrass. In late July a natural population of black cutworms (Agrotis ipsilon (Hufnagel) the number of visible feeding centers per plot were counted. Data were subjected to an ANOVA using ARM and the Tukeys multiple mean comparison test.

Dollar spot data are in table 1. Brown patch data are shown in table 2. Civitas+Harmonizer (aka Civitas 2 Pack) and Civitas 1 Pack and Civitas+propiconazole 1Pack (with anti-settling agent) performed very well and had significantly disease when compared to the untreated control. The largest impact on turfgrass quality was dollar spot and brown patch severity. Generally, treatments providing the highest level of dollar spot had the highest quality.

In late July a natural population of black cutworms (Agrotis ipsilon (Hufnagel) invaded the plots. There was an agronomically important reduction in black cutworms in plots receiving Civitas+Harmonizer and Civitas 1 Pack.

The data demonstrate that Civitas 1 Pack provided good control in dollar spot and brown patch control.
